One of the fastest recorded speeds of a turtle while swimming is 9 m/s. Approximately, what is this speed in kilometers per hour
2 answers:
Answer: 32.4 km/h.
Step-by-step explanation:
This is a simple conversion of units, so we're going to use conversion factors. A conversion factor is used to change the units of a measured quantity without changing its value.
The unity bracket method of unit conversion consists of a fraction in which the denominator is equal to the numerator, but they are in different units; since the numerator and denominator are equal, the fraction is equal to one and it won't affect the value of the quantity. Here's how you do it:
As you can see, the seconds and meters cancel each other and you're left with km/h.

<h2>The time needed is 10 months.</h2>Step-by-step explanation:
The given points are (0, 3500) and (5, 1750).
First, we use the formula below to find the slope of the line
Which means the function is deacrasing with a ratio of 350 feet per month.
Now, we use the slope and one point to find the equation
This linear function shows that the situation started at the y-intecept (0, 3500), which means the month 0 had already 3500 feet. In other words, the total distance is 3500 feet. Now, the x-intercept will tell us the time needed to travel that distance.
Therefore, the time needed is 10 months.
